The purge of the Red Army was supported by fabricated evidence that German counter-intelligence had introduced through an intermediary, President Beneš of Czechoslovakia. This forged evidence purported to show correspondence between Marshal Tukhachevsky and members of the German high command. However the actual evidence introduced at trial was obtained from forced confessions. The purge of the army removed 3 of 5 marshals, 13 of 15 army generals, 8 of 9 admirals, 50 of 57 army corps generals, 154 out of 186 division generals, 16 of 16 army commissars, and 25 of 28 army corps commissars.
